Fierce protest of the President of the United States is welcome — imperative, actually, when he's wrong. At least until President Trump, who calls the "fake news" media the "enemy of the people," manages to turn the libel laws into a weapon to quash dissent, it's a free country.

Staring coldly into the camera, she holds the bloody, severed head of the leader of the free world up for all to see.

It's free expression — political expression at that, which means it's due the highest protections the Constitution's First Amendment can afford. And it's absolutely repulsive and Griffin's apology after a justified uproar doesn't make it any less repulsive.
